[Bluez-devel] boot vs. report protocol

["Ortwin Glück" <odi@odi.ch>]

Hi,

In net/bluetooth/core.c there is:

	if (session->input) {
		hidp_send_ctrl_message(session,
			HIDP_TRANS_SET_PROTOCOL | HIDP_PROTO_BOOT, NULL, 0);
		session->flags |= (1 << HIDP_BOOT_PROTOCOL_MODE);

		session->leds = 0xff;
		hidp_input_event(session->input, EV_LED, 0, 0);
	}


which effectively sets the boot protocol for all input devices. To
support some scroll wheel mice they need to be put into report mode, though:

	if (session->input) {
		hidp_send_ctrl_message(session,
			HIDP_TRANS_SET_PROTOCOL | HIDP_PROTO_REPORT, NULL, 0);

		session->leds = 0xff;
		hidp_input_event(session->input, EV_LED, 0, 0);
	}

I assume that's safe. Solaris for instance, initializes all devices in
report mode by default. It never even tries boot protocol.

Maybe it would make sense to have a userspace interface to switch the
mode from within hidd.
